If this goes back up to 78.50 that would tell me that it tested resistance that it broke and that is now support. Then there is a large gap to the upside it could fill. Stock has a low float and very high short ratio.
This stock has a 55% short float. If the price breaks resistance and hits 55 on good volume, shorts are probably going to start covering their positions and buying.
Found on chartmill with a 5 star setup rating. News shows motley fool just recommended it as well and an analyst recently upgraded it.
